Abstract:
An experiment was conducted with BRRI dhan 28 following four irrigation treatments (flood, drip, alternate wetting and drying, sprinkler) and two tillage methods (conventional or puddled and unpuddled). Highest number of weed infestation over conventional tillage was observed when herbicide was not applied. Weed biomass was recorded maximum in sprinkler irrigation followed by alternate wetting and drying (AWD) and flood irrigation. The main type of weed in the rice field was sedges. Weed infestation at 20 and 40 days after herbicide application was found to be the highest due to sprinkler irrigation over AWD and flood irrigations. Unpuddled tillage showed lower weed number and biomass over the conventional puddle tillage. Dhaka Univ. J. Biol. Sci. 24(2): 131-136, 2015 (July)

Abstract:
The effect of flood irrigation on clover nitrogen fixation (acetylene reduction activity) was investigated in unfertilized pastures and pastures fertilized with 100 kg N/ha as NH4N03. During the experiment acetylene reduction activities were monitored between successive flood irrigations. The rate of ethylene production increased with decreasing soil water content, peaking 13 days after irrigation. Measured nodule activity then declined, possibly owing to water stress. Nitrogen fertilizer reduced acetylene reduction activities to about half that of the unfertilized pastures. For most of the irrigation cycle acetylene reduction by the pasture was below the measured maximum.

Abstract:
This paper studies primary canals of three traditional irrigation systems in the southern plains of Nepal. It offers a scientific interpretation of the indigenous technology applied to the systems, which facilitates to use the same channel network for irrigation, drainage and flood management. The flood management technology of the farmers by diverting as much discharge as possible to the field channels results in the reduction of discharge towards the downstream part of the main channel. It is depicted in the simulation study that uses the river analysis program HEC-RAS 4.0. A cascade of weirs is found to be the most cost effective and user-friendly option to upgrade these systems preserving the existing irrigation, drainage as well as flood management functions. This study suggests that the conventional irrigation design principles should be applied very cautiously with full knowledge of the existing socio-institutional setting, hydro-ecological regime and indigenous technology for upgrading any traditional irrigation system successfully. The indigenous flood management technology strengthens the emerging concept that the floods in the Ganges plain are to be managed, not controlled.

Abstract:
Studies suggest that disturbance-induced reductions in soil seedbank density are diminished by periods of water scarcity after soil disturbance; however, this hypothesis has yet to be tested. The objectives of this study were (1) to determine the effects of increasing time between soil disturbance and flood irrigation on disturbance-induced reductions in soil seedbank density, and (2) to identify specific soil moisture levels that cause seedbank reductions under flood irrigation. Weed species in this study were junglerice, Palmer amaranth, and yellow foxtail. For Objective 1, artificial seedbanks with known numbers of seeds were disturbed 10, 3, or 0 d prior to flood irrigations under field conditions. For Objective 2, seeds were buried in soil mesocosms that were hydrated to specific soil water potentials (flooded, 0 kPa, −30 kPa, −60 kPa, and −180 kPa) and placed in laboratory conditions favorable for germination. For both objectives, seeds were recovered to determine the percentages of buried seeds that survived the disturbance or moisture treatments. Results for the field study indicated that soil disturbances reduced seedbank persistence of Palmer amaranth but did not affect seedbank persistence of junglerice and yellow foxtail. Disturbance-induced reductions in seedbank density were greatest when soil was disturbed 0 and 3 d prior to flood irrigations. For the laboratory study, results showed that waterlogged soil was not required for seedbank losses because rates of seedbank persistence were greater in saturated soils (0 kPa and flooded) compared to the lower moisture levels. These studies indicate that delays in irrigation can reduce the seedbank reduction potentials of soil disturbance events. Further, irrigation timing effects on disturbed soil seedbanks are likely to occur in all irrigation systems, including those that reduce the amount of water applied compared to flood irrigation.

A study conducted in the Malaprabha command area revealed that border strip method of irrigation was found better in terms of yield, income and water savings in cultivation of wheat. The crop yield was higher in border strip method of irrigation (28.50 q/ha) over flood (20.90 q/ha). The net returns was also higher in border strip method of irrigation (Rs. 20851.01/ha) over flood (Rs. 8024.92/ha). The highest cost of irrigation was found in flood method of irrigation (Rs. 2898.47/ha) compared to border strip method of irrigation (Rs. 2051.13/ha). The highest water consumption was seen under flood method of irrigation (12.04 ha cm) followed by border strip method of irrigation (8.41 ha cm).

Full text
Abstract:
Runoff from flood-irrigated perennial pastures generally contains higher phosphorus (P) and nitrogen (N) concentrations than the irrigation water applied to the pastures. We examined the sources of P and N that could contribute to these elevated nutrient concentrations in runoff.The first experiment compared P and N losses in runoff from pasture cut to different residual pasture masses. Flow-weighted P and N concentrations and loads were about 100% higher from pasture cut to 47�mm above ground than from pasture standing at 155 mm. These results indicated that severely defoliated pasture may be a significant source of nutrients when flood irrigated.In the second experiment, pastures were defoliated at a single grazing with different stocking intensities and the flow-weighted P and N concentrations in runoff were determined during 4 successive flood irrigation events. Nitrogen and P concentrations in runoff after the first irrigation following defoliation were higher at the highest stocking intensity. However, the effect of the grazing on nutrient concentrations in runoff declined in subsequent irrigation events. A regression model fitted to the P data indicated that there was a significant linear increase in P concentrations with stocking density and a significant non-linear decline in concentrations with successive irrigations. A similar relationship for TKN concentrations in runoff at each stocking density over the 4 irrigation events was not found. An inconsistency of the TKN concentrations of the supply water between irrigation events possibly helped to mask a similar relationship between N concentrations in runoff and stocking density over the 4 irrigation events. We postulate that both animal excreta and the pasture itself can contribute to elevated nutrient concentrations in flood-irrigation runoff.

Abstract:
The north-east region of Victoria is an important water-harvesting catchment for gravity-fed irrigators downstream of Lake Mulwala. Dairy farmers are significant users of irrigation water in north-east Victoria but little was known about their irrigation practices and attitudes. A survey undertaken in 2000 collected data on irrigation practices and attitudes from 92% of the irrigating dairy farmers in the region. It found diversity in many aspects of irrigation amongst the region’s irrigated dairy farms, ranging from the proportion of the farm irrigated to the irrigation system used, and identified areas where improvements to irrigation practices could be made. More than 8 different irrigation systems were used in the region, and flood irrigation was the most commonly used. However, a large proportion (37%) of flood irrigators were contemplating changing to spray irrigation, mostly to long lateral hand move sprinkler irrigation, in an effort to improve water use efficiency. More than 50% of respondents did not meter irrigation water use, and 83% pumped water directly from rivers or creeks, with dams and dragline holes the next most common sources. Irrigation scheduling (when to start irrigating and the frequency of irrigation thereafter) and the amount of water to apply were generally based on knowledge and experience rather than on soil moisture monitoring equipment or use of evaporation rates. Most survey respondents recognised that their irrigation practices could improve and said that they would be interested in information to help them make more informed decisions about irrigation practices.

Abstract:
Flood irrigation in the winter has been widely applied in northwest China for several years, but little attention has been paid to the flood irrigation program to date. In order to seek a reasonable irrigation quota, a flood irrigation experiment using two common quotas (1,800 and 1,200 m3 ha−1) was conducted in an area irrigated by saline water in the Nanjiang basin with shallow groundwater. Soil electrical conductivity in six treatments irrigated by saline water, with various salinity backgrounds, was investigated using Hydra and DDS-307 before and after flood irrigation. The results indicate that the quota of 12,00 m3 ha−1 was small enough to prevent soil salt from leaching out of the root zone. Although the quota of 1,800 m3 ha−1 may guarantee regular plant growth in the following year, it resulted in at least 267.2 g m−2 of salt entering the shallow groundwater. Therefore, flood irrigation had an important and profound effect on plants, soil environment, and shallow groundwater. The quota of flood irrigation in winter should be determined cautiously according to the hydraulic characteristics and salt background of the soil.

Abstract:
Groundwater contamination by nitrate and other chemicals is a public concern and has subjected agriculture to scrutiny. Field studies were conducted at the Maricopa and Marana Agricultural Centers in 1989 to 1990 to document nitrate leaching potential with border flood irrigation. Calcium nitrate fertilizer was applied at various rates along with potassium bromide, which serves as an additional indicator of nitrate movement. Approximately 8.55 inches of irrigation water was applied at the Maricopa site on a sandy loam soil and 4.0 inches of irrigation water was applied at the Marana site on a clay loam soil. At the Maricopa site, only 64% of the nitrate could be accounted for in the top 6.7 ft. while most of the nitrate was found in the top 4 to 5 ft. at Marana. The water and nitrate moved 3 to 4 times deeper than predicted in the absence of preferential flow.

Abstract:
In Bangladesh flood mitigation strategies have concentrated on embankments. However, due to a perceived lack of success with this strategy and high returns to irrigation development, the emphasis in water management switched towards small scale irrigation. Serious floods in 1987 and 1988 have renewed interest in flood mitigation. However, there is a lack of detailed evidence on the impacts of embankments. This study provides just such evidence. The study comprises a detailed post-evaluation of a major flood control, drainage and irrigation project, the Chandpur Irrigation Project. The results show that the project has been successful in reducing normal monsoon water levels, with consequent changes in cropping patterns to higher yielding varieties. However, a with-without comparison revealed that expected yields (allowing for risks of flooding and drainage problems) were less than predicted due to drainage problems within the project, whereas non-project expected yields are as predicted. Hence agricultural output has increased substantially, but output and its value are less than anticipated. Household incomes in the project are 25&37 higher (on average) than in control areas, but this is because larger landowners have gained from greater returns to agriculture (for example, from preferential access to irrigation), and diversifying into other occupations. Some households have gained by selling land and obtaining salaried jobs elsewhere or by becoming traders. By comparison small landowners may be slightly less prone to losses in flood years but have not moved into surplus. Landless labourers have similar incomes inside and outside the project; real wages are unchanged, and increased work has not compensated for population growth. Inside the project changes in landholding category have been fewer than outside. Open water fish populations have been reduced by the embankment, particularly affecting poor households. However, fish cultivation has expanded more than in flood prone areas, benefiting pond owners and enabling professional fishermen to maintain their incomes (at the cost of greater dependence on larger landowners). Improved methods of post-evaluation (which have implications for appraisal of new projects) are developed to incorporate flood risks and consequent yield reductions and non-agricultural damages, and to standardise economic valuation. Applying these methods revealed that the Chandpur Project has been, despite an uneven distribution of benefits, relatively successful (an economic rate of return of at least 5%). Although there are some project specific reasons for this success, this project has suffered many problems typical of embankment in Bangladesh. Hence embankments are potentially important for the future economic development of Bangladesh - by reducing damage and disruption and increasing agricultural output. The study concludes with recommendations for improved flood plain planning in Bangladesh, using detailed flood loss data and improved appraisal methods, to ensure that choice of flood mitigation strategies and investments are rational, and that all public investments take flood risks into account.

Abstract:
The Elk Ranch hayfield in Grand Teton National Park (GTNP) has been historically flood-irrigated since the early 20th Century. The park service is now considering closing irrigation to restore native plant communities and enhance Spread Creek fisheries and will need information on the extent of irrigation-created wetlands and how irrigation cessation would change the vegetative component of the ranch. The main objective of this study was to assess the relation between soil and vegetation characteristics of wetland community types at the ranch and to determine if any of the relationships could be used to differentiate between naturally occurring and irrigation created wetlands. Vegetation data were collected from transects centered on a soil pit at 28 randomly located sample points throughout the hayfield. Twenty-six of the 28 sample plots were classified as wetland based on criteria listed by the US Fish and Wildlife Service. Bray-Curtis dissimilarity and nonmetric multi-dimensional scaling were used to analyze percent foliar cover, wetland index value (WIV), soil texture, percent organic matter, redox contrast and abundance, and depth to groundwater and soil saturation for each of the sampled points. The WIV and redox contrast had the greatest dissimilarity (D2), 0.90, and 0.71 respectively across the hayfield. The other measured characteristics had D2 values ranging from 0.23 to 0.49 and were strongly correlated with the WIV and redox contrast measures. However, inclusion of these measures contributed little to the differences already identified. Categorical organization of WIV and redox measures indicated that naturally occurring wetlands could be differentiated from wetlands created by flood irrigation in former upland vegetation communities. Combining wetland index value and soil redox contrast suggests park managers could identify wetland community types likely to remain or transition following cessation of flood irrigation at the Elk Ranch. Additional testing at other GTNP sites will be necessary to test the broad application of this approach and refine the assessment categories.

Abstract:
Land application of wastes has become increasingly popular, to promote nutrient recycling and environmental protection, with soil functioning as a partial barrier between wastes and groundwater. Dairy shed effluent (DSE), may contain a wide variety of pathogenic micro-organisms, including bacteria (e.g. Salmonella paratyphyi, Escherichia coli. and Campylobacter), protozoa and viruses. Groundwater pathogen contamination resulting from land-applied DSE is drawing more attention with the intensified development of the dairy farm industry in New Zealand. The purpose of this research was to investigate the fate and transport of bacterial indicator-faecal coliform (FC) from land-applied DSE under different irrigation practices via field lysimeter studies, using two water irrigation methods (flood and sprinkler) with contrasting application rates, through the 2005-2006 irrigation season. It was aimed at better understanding, quantifying and modelling of the processes that govern the removal of microbes in intact soil columns, bridging the gap between previous theoretical research and general farm practices, specifically for Templeton soil. This study involved different approaches (leaching experiments, infiltrometer measurements and a dye infiltration study) to understand the processes of transient water flow and bacterial transport; and to extrapolate the relationships between bacterial transport and soil properties (like soil structure, texture), and soil physical status (soil water potential ψ and volumetric water content θ). Factors controlling FC transport are discussed. A contaminant transport model, HYDRUS-1D, was applied to simulate microbial transport through soil on the basis of measured datasets. This study was carried out at Lincoln University’s Centre for Soil and Environmental Quality (CSEQ) lysimeter site. Six lysimeters were employed in two trials. Each trial involved application of DSE, followed by a water irrigation sequence applied in a flux-controlled method. The soil columns were taken from the site of the new Lincoln University Dairy Farm, Lincoln, Canterbury. The soil type is Templeton fine sandy loam (Udic-Ustochrept, coarse loamy, mixed, mesic). Vertical profiles (at four depths) of θ and ψ were measured during leaching experiments. The leaching experiments directly measured concentrations of chemical tracer (Br⁻ or Cl⁻) and FC in drainage. Results showed that bacteria could readily penetrate through 700 mm deep soil columns, when facilitated by water flow. In the first (summer) trial, FC in leachate as high as 1.4×10⁶ cfu 100 mL⁻¹ (similar to the DSE concentration), was detected in one lysimeter that had a higher clay content in the topsoil, immediately after DSE application, and before any water irrigation. This indicates that DSE flowed through preferential flow paths without significant treatment or reduction in concentrations. The highest post-irrigation concentration was 3.4×10³ cfu 100 mL⁻¹ under flood irrigation. Flood irrigation resulted in more bacteria and Br⁻ leaching than spray irrigation. In both trials (summer and autumn) results showed significant differences between irrigation treatments in lysimeters sharing similar drainage class (moderate or moderately rapid). Leaching bacterial concentration was positively correlated with both θ and ψ, and sometimes drainage rate. Greater bacterial leaching was found in the one lysimeter with rapid whole-column effective hydraulic conductivity, Keff, for both flood and spray treatments. Occasionally, the effect of Keff on water movement and bacterial transport overrode the effect of irrigation. The ‘seasonal condition’ of the soil (including variation in initial water content) also influenced bacterial leaching, with less risk of leaching in autumn than in summer. A tension infiltrometer experiment measured hydraulic conductivity of the lysimeters at zero and 40 mm suction. The results showed in most cases a significant correlation between the proportion of bacteria leached and the flow contribution of the macropores. The higher the Ksat, the greater the amount of drainage and bacterial leaching obtained. This research also found that this technique may exclude the activity of some continuous macropores (e.g., cracks) due to the difference of initial wetness which could substantially change the conductivity and result in more serious bacterial leaching in this Templeton soil. A dye infiltration study showed there was great variability in water flow patterns, and most of the flow reaching deeper than 50 cm resulted from macropores, mainly visible cracks. The transient water flow and transport of tracer (Br⁻) and FC were modelled using the HYDRUS-1D software package. The uniform flow van Genuchten model, and the dual-porosity model were used for water flow and the mobile-immobile (MIM) model was used for tracer and FC transport. The hydraulic and solute parameters were optimized during simulation, on the basis of measured datasets from the leaching experiments. There was evidence supporting the presence of macropores, based on the water flow in the post-DSE application stage. The optimised saturated water content (θs) decreased during the post-application process, which could be explained in terms of macropore flow enhanced by irrigation. Moreover, bacterial simulation showed discrepancies in all cases of uniform flow simulations at the very initial stage, indicating that non-equilibrium processes were dominant during those short periods, and suggesting that there were strong dynamic processes involving structure change and subsequently flow paths. It is recommended that management strategies to reduce FC contamination following application of DSE in these soils must aim to decrease preferential flow by adjusting irrigation schemes. Attention needs to be given to a) decreasing irrigation rates at the beginning of each irrigation; b) increasing the number of irrigations, by reducing at the same time the amount of water applied and the irrigation rate at each irrigation; c) applying spray irrigation rather than flood irrigation.

Abstract:
Les conditions de vie offertes par la montagne anti-atlasique aux populations ne sont guère favorables au travail de la terre : la pluviosité est très irrégulière et insuffisante, le sol est squelettique et caillouteux car il se développe à partir d'un substrat géologique ancien et sur des pentes fortes. Pour pallier ces conditions hostiles, la société montagnarde de l'Anti-Atlas marocain s'est efforcée depuis des siècles, peut-être même depuis des millénaires, d'aménager pratiquement toutes les pentes pour y fixer la terre arable et surtout pour y récupérer tout le ruissellement pluvial afin d'en imbiber les terres. Ces aménagements sont aujourd'hui parfois fossilisés par l'abandon de l'activité agricole et sont menacés de ruine ou de disparition. Cette situation est évidente dans toutes les contrées anti-atlasiques que nous avons parcourues. C'est une oeuvre et un savoir-faire paysans qui sont donc en danger. Il est important de les étudier alors que ces artefacts sont encore partiellement fonctionnels et qu'ils peuvent encore participer à l'enrichissement du potentiel culturel de cette montagne méridionale déjà si riche, par ailleurs, de paysages et de vestiges architecturaux de toute sorte
The living conditions of the population in the Anti-Atlas Mountains are not ideal for agriculture: rains are very irregular and insufficient; the soil is skeletal and stony, as it develops from an old geological substratum and on steep slopes. To make up for those hostile conditions, for centuries and perhaps for millennia, the mountain society of the Moroccan Anti-Atlas has endeavoured to manage the slopes so as to preserve arable land and especially to capture rainfall runoff, so as to imbibe the land with it. Nowadays, those structures are sometimes fossilized and threatened with disrepair and destruction now that agricultural activities have come to an end. This situation is striking in all the Anti-Atlas areas I have travelled through. The work and the skills of local farmers are therefore in danger of being lost. It is essential to study those artifacts while they are still partly functional, as they can still enrich the cultural potential of this southern mountainous area, already rich of its many landscapes and architectural vestiges

Abstract:
The rice culture for Rio Grande do Sul economy is of great relevance. Annually, around one million of hectares are planted. As it is a culture irrigated by a continuum flood, the supply of the high hydric demand is done in 70% of the area through pumping station, representing a significant portion of the production costs. Associate with this fact, there is a necessity in reducing water and energy consumption, object of several official and private actions undertaken in the latest years with the object of preserving the sources, reducing costs and contouring conflicts in the water access. The objective of this work was to find an easily and quickly way of planning, trying to help the extensions of the pumping station to rice irrigation. Real known data were used related to the ground-plant-climate system of the Central Depression rice culture region, doing a calculation based in the simplified hydric balance adapted to the rice farming system. Instantaneous hydric demands were calculated for the initial flood and for the maintenance of the flood until the end of the irrigation cicle. To reduce either outflows or installed powers was adopted a division of the total areas established in the simulation (between 10 and 190 ha), and after was done a temporal stagger of the sowing and the irrigation process. A reduction of 64% in the outflow of the initial flow was attained and 63% in the installed electrical powers of the pumping station, when compared to the simultaneous flow process of the farming total areas. When it was used the regression analysis, were got equations for outflows adjustment and required power in operation of total areas for estimations in the intervals of the adopted areas in the work. The resource makes possible the previous planning of farmings relating to the instantaneous demand for initial flow and support supply, as well as in relation to the electrical powers, observing pumping stations in installations in parallel (two or more pump motor system) sets. Another possible application refers to the procedures of elaborating Basin Administrative Committees and corresponding processes of warranting right of water use, in order to offer basic and trustful information to establish maximum cultivable areas because of the minimum availabilities established regionally to the activity.
É incontestável a relevância da cultura do arroz para a economia do Rio Grande do Sul. São plantados anualmente em torno de um milhão de hectares, os quais são irrigados por inundação contínua, exigindo elevada demanda hídrica. O suprimento hídrico do cultivo é atendida em 70% da área através de sistemas de recalque (bombeamento), representando uma parcela apreciável do custo de produção e compreendendo, entre custos diretos e indiretos, 27% do custo total. Evidencia-se assim a necessidade de redução no consumo de água e energia, objeto de várias ações oficiais e privadas empreendidas nos últimos anos com vistas a preservar os mananciais, reduzir custos e contornar conflitos no acesso à água. O foco do presente trabalho voltou-se para a busca de uma ferramenta de planejamento de fácil e ágil aplicação, visando subsidiar os dimensionamentos de sistemas de recalque para a irrigação do arroz. Partiu-se de dados reais típicos relativos ao sistema solo-planta-clima da Região Orizícola da Depressão Central, estabelecendo-se um procedimento de cálculo baseado no balanço hídrico simplificado adaptado ao sistema lavoura de arroz . Foram calculadas as demandas hídricas instantâneas para as fases de inundação inicial e para a manutenção da inundação até o final do ciclo de irrigação. Objetivando a redução tanto das vazões quanto das potências instaladas, foi adotado um fracionamento das áreas totais estabelecidas na simulação (entre 10 e 190ha, em incrementos de 20ha), com conseqüente escalonamento temporal do processo de irrigação. Atingiu-se dessa forma uma redução de até 64% na vazão de inundação inicial e de até 63% na potência instalada elétrica dos sistemas de recalque, quando comparados a processo de inundação simultânea das áreas totais das lavouras. Aplicando análise de regressão foram ajustadas equações que permitem estimar vazões e potências requeridas em função de áreas totais de lavoura no intervalo de áreas da simulação. Este recurso possibilita o planejamento de lavouras no tocante às vazões mínimas requeridas para inundação inicial e para o suprimento de manutenção, bem como em relação ao pré-dimensionamento das potências elétricas mínimas correspondentes, contemplando sistemas de recalque na modalidade de instalações em paralelo (dois ou mais conjuntos motor-bomba). Foram igualmente calculados os módulos de irrigação (vazões específicas expressas em l.s-1.ha-1) para as fases de inundação inicial e de manutenção. Os resultados obtidos permitem aplicações no planejamento regional (alocação de recursos hídricos), no planejamento de formação de lavouras, na estimativa de volumes totais de demanda, em prédimensionamentos de estações de bombeamento, em ações de re-engenharia de instalações existentes e no processo de outorga de direito de uso da água.

Abstract:
AbstractThe rapidly changing global climate due to increased emission of anthropogenic greenhouse gases (GHGs) is leading to an increased occurrence of extreme weather events such as droughts, floods, and heatwaves. The three major GHGs are carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). The major natural sources of CO2 include ocean–atmosphere exchange, respiration of animals, soils (microbial respiration) and plants, and volcanic eruption; while the anthropogenic sources include burning of fossil fuel (coal, natural gas, and oil), deforestation, and the cultivation of land that increases the decomposition of soil organic matter and crop and animal residues. Natural sources of CH4 emission include wetlands, termite activities, and oceans. Paddy fields used for rice production, livestock production systems (enteric emission from ruminants), landfills, and the production and use of fossil fuels are the main anthropogenic sources of CH4. Nitrous oxide, in addition to being a major GHG, is also an ozone-depleting gas. N2O is emitted by natural processes from oceans and terrestrial ecosystems. Anthropogenic N2O emissions occur mostly through agricultural and other land-use activities and are associated with the intensification of agricultural and other human activities such as increased use of synthetic fertiliser (119.4 million tonnes of N worldwide in 2019), inefficient use of irrigation water, deposition of animal excreta (urine and dung) from grazing animals, excessive and inefficient application of farm effluents and animal manure to croplands and pastures, and management practices that enhance soil organic N mineralisation and C decomposition. Agriculture could act as a source and a sink of GHGs. Besides direct sources, GHGs also come from various indirect sources, including upstream and downstream emissions in agricultural systems and ammonia (NH3) deposition from fertiliser and animal manure.

Abstract:
In Iraq, the two dominating surface water sources are Tigris and Euphrates Rivers in which some dams constructed on both of them forming reservoirs. Haditha Dam reservoir is one of the most essential sources of drinking, irrigation, flood control and hydropower generation in Anbar State, Western Part of Iraq. Besides, the reservoir is a unique habitat with a wide spectrum of biodiversity. The objective of this study is to investigate and monitor the water quality in Haditha Dam reservoir and introduce the Multi Criteria Analysis (MCA) to highlight the best runoff control measure depending on selected criteria and criteria weights. Experts were interviewed for the selection of criteria and for the assignment of the weight factor and scores. Four criteria from three categories such as technical, economic and environmental aspects were selected. Results from this study indicated that a distinguished difference in TSS and Turbidity between the dry and wet seasons and necessitates the installation of runoff control measures. It was found that the soil binders, sediment basin and diversion channel are the best alternatives for controlling erosion, sediment and drainage respectively. The sensitivity analysis showed very strong decision made by the experts for the technical, economic and environmental criteria.
