There is a growing threat of urban flooding, particularly in Pakistan that needs attention and requireseffective management strategies. The chief trigger for urban flooding is the rapid and unplanned urbanization in areaswhere impermeable surface inhibits rainwater diffusion and changes the natural water flow. In many developedcountries, a technique of rainwater harvesting is implemented as a sustainable strategy to manage urban stormwater.Most studies and projects chiefly focused on the potential use of the Rainwater harvesting technique for waterconservation in arid and semi-arid climates. In the present work, GIS and remote sensing methodologies are utilized forthe suitability of rainwater harvesting structures. This study was conducted in Lahore, the second most populated cityof Pakistan and the capital of Punjab. Generally, the water harvesting technique depends on topographical areas withwater accumulation, where there is an availability of open spaces in the form of green areas and barren lands, rainfall,drainage network density, and rainfall distribution, particularly in the urban environment. The SRTM DEM data wereused for finding high water accumulated areas, and the Landsat OLI image is used to retrieve land use information i.e.vacant land and open green spaces, existing drainage network density, and rainfall distribution. All these layers wereintegrated through AHP to detect the potentially suitable sites for the construction of rainwater harvesting structures.Results concluded 94 suitable sites with categorization from highly to critically suitable for the construction ofrainwater harvesting structures in which 6 were highly suitable areas in Data Gunj Bakhsh Town and Ravi Town.Besides, residential areas are having a maximum site suitability percentage, followed by roads, agricultural and openspaces in the area under consideration. Considering the suitable sites, further rainwater harvesting methods can beidentified in the study area to alleviate urban flooding and improve the urban environment.

Abstract: Rainwater harvesting is a technique for collecting rainwater that would otherwise be wasted, mainly in metropolitan settings. There is essentially no infiltration and percolation due to the completely different land use compared to the metropolitan region. As a result, groundwater levels have been steadily depleted. Rainwater harvesting is nearly completely unknown among the general public. There is a lack of community planning that may result in widespread participation and so replenish the groundwater table. The current research looks at several rainwater gathering techniques and how they may be implemented at the chosen location. The research is being conducted on the Dehradun campus of UPES. The focus is mostly on the water collected on the rooftop, which will be filtered and used for cleaning and gardening. Because it is a hilly location, the region receives a lot of rain, which provides excellent opportunities for rainwater gathering. The total runoff from the entire rooftop is calculated using a rational formula and then distributed to various uses. The paper's main goal is to advocate the wise use of this valuable resource while keeping in mind the economics of the method used. Keywords: Rainwater harvesting, rational formula, groundwater.

This research paper focuses on the design of a rainwater collection system and the possible use of harvested rainwater in a kindergarten building to promote water conservation. Rainwater harvesting is an old technique but increasing in use because of the natural rainwater quality and to reduce the treated water consumption. Harvesting rainwater is considered an alternative source in the field of integrated water resources management and can be approved in many buildings to improve water conservation. In Tirana, there is a little experience in rainwater harvesting, since the availability of freshwater resources hasn't been a problem yet. Once we have studied all the key components needed to design a rainwater collection system, we got a kindergarten building with a catchment area of 370 m2. Rainwater that will be collected will be used for the daily requirements of the building, in flushing toilets, washing machines, and watering the garden. A system of rainwater harvest reduces potable water use, decreases ongoing operating costs for the kindergarten, and prevents storm runoff that would negatively impact the environment.

Rainwater utilization has great potentials for recovering hydrological cycles, for buffering extreme run-off situations in the watercourses, and for reducing the costs for water supply in urban area. However, little information is available on the water qualities and runoff properties of collected rainwater, which is critical for efficient design and maintenance strategies of rainwater harvesting facilities. In this study, characteristics of rainwater collected in a rainwater harvesting system were examined in terms of pollutant concentrations. Based on these results, TiO2 photocatalysts were applied on the roof surface as a novel coating material to improve the quality of collected rainwater. The analysis of rainwater samples shows that the contamination by turbidity, conductivity, and color occurs during the catchment process, which may result in troubles for further use. The roof coating technique developed in this study appeared to be effective in increasing the wash-off of pollutants and improving the water quality in roof runoff because of its increased hydrophililicy as well as photocatalytic reactivity. Further research is required on trace pollutants such as endocrine disruptors to estimate and minimize health risk in rainwater harvesting.

Rainwater harvesting (RWH) feels right from a long-term sustainability perspective. Short-cutting the hydrological cycle seems to make logical sense from an environmental stance, and the technique is being driven into new buildings in the United Kingdom (UK) through building rating systems which are in turn pushed by government policy. However, little work has been done to assess its environmental credentials from a whole life perspective. Controversially, those studies that have been done have found that RWH systems tend to have greater environmental impacts than mains supply infrastructure. This work seeks to investigate the latest studies, and provide a way forward in the debate.

Based on theoretical analysis and comparison, it is sure that urban rainwater collection and reuse have no negative effect on urban water circulation and downstream eco-environment. It is shown from the results that rainwater collection and reuse would not reduce volume of rainwater infiltration. It also could control runoff pollution and reduce the flood peak of downstream river in flood season. Thus, rainwater harvesting was an effective approach to improve the eco-environment of downstream river. It could be concluded that the technique could be applied to different areas to improve local conditions.

Rainwater harvesting (RWH) is one of the essential alternative sources of water that may be used. However, finding potential RWH locations on a broad scale has always been challenging, requiring further research. The effectiveness of RWH structures depends on their design and the selection of suitable sites. This study aimed to select potential sites for rainwater harvesting in the Garmian region of Kurdistan-Iraq, using GIS and Remote Sensing (RS) techniques. Two multicriteria analysis (MCA) techniques: the analytical hierarchal process (AHP) and Fuzzy analytical hierarchal process (FAHP) were used for comparison purposes to identify potential RWH sites. A suitability map of potential RWH systems was then generated following the weighted linear combination (WLC) and the Fuzzy Gamma methods. The outcomes showed that, unlike most recent studies, which relied on the minimum and maximum local rainfall values, a minimum agreed-upon rainfall depth should be used as a benchmark when classifying rainfall to obtain realistic results. The findings also showed that 9.7%, 43.4%, 33.6%, and 13.3% of the sites have very high, high, moderate, and low suitability for rainwater harvesting, respectively, depending on the suitability map produced by the WLC method. However, the outcome of the Fuzzy Gamma technique appeared more realistic and revealed that 10.6%, 15.6%, 26.6%, 21.9%, and 25.3% of the sites have very high, high, moderate, low, and very low appropriateness for rainwater harvesting, respectively. The methods adopted in this study can be helpful for researchers in the field of RWH to achieve reliable results. Also, this study’s findings can assist in well-organized water resource management planning to ensure sustainable water development in the Garmian region.

Urban area like Dhaka City, in Bangladesh, has scarcity of safe drinking water which is one of the prominent basic needs for human kind. This study explored the acceptability of harvested rainwater in a densely populated city like Dhaka, using a simple and low cost technology. A total of 200 random people from four slums of water-scarce Dhaka City were surveyed to determine the dwellers' perception on rainwater and its acceptability as a source of drinking water. The questionnaire was aimed at finding the socio-economic condition and the information on family housing, sanitation, health, existing water supply condition, knowledge about rainwater, willingness to accept rainwater as a drinking source etc. A Yield before Spillage (YBS) model was developed to know the actual rainwater availability and storage conditions which were used to justify the effective tank size. Cost-benefit analysis and feasibility analysis were performed using the survey results and the research findings. The survey result and overall study found that the low cost rainwater harvesting technique was acceptable to the slum dwellers as only the potential alternative source of safe drinking water.

Abstract In the face of increasing water scarcity aggravated by climate change, the rainwater harvesting system is a technique that increases the water supply for various purposes. The objective of this research is to analyse the recent literature published on the rainwater collection system, for which the systematic review method was used. The main form of rainwater catchment are roofs, but the material used is important because it can affect the quality of the water. Some physicochemical parameters of rainwater may be within the standards for human consumption, but it is contaminated by pathogenic microorganisms, which represents a risk to public health if it is consumed without prior treatment, so it is mainly used for irrigation and flushing toilets. However, this system has been implemented mainly in rural areas to satisfy their basic needs, including human consumption, because these places do not have access to the central drinking water system. Given this scenario, treatment technologies are being developed that are easy to operate and maintain, such as solar disinfection and filtration for drinking water purposes. This study provides a global overview progress of research related to the rainwater harvesting system.

Rainfall in semi-arid areas is generally insufficient to meet crop water requirements, and above all erratic in distribution. This leads to crop yield fluctuation, which drastically affects food security. Rainwater harvesting technologies have been implemented in these areas in order to mitigate the effect of perennial droughts. The successful adoption of these technologies can contribute to poverty alleviation, and therefore improve the livelihood of resource-poor subsistence farmers. Field trials for testing different rainwater harvesting scenarios are expensive, time consuming and laborious. As a result, crop models must be used to help study these systems, and thereby make prudent water harvesting design choices for specific situations. For this purpose, a simple, one-dimensional soil water balance model (Soil Water Balance-SWB) was modified by incorporating linear runoff estimation models in order to predict the soil water balance and crop yield under different rainwater harvesting design scenarios and to select the design most likely to succeed in a particular locality. Field data collected during the 2007/2008 maize growing season, on sandy clay loam soils, at the Hatfield Experimental Farm of the University of Pretoria, was used to parameterize the different runoff models and to calibrate the SWB crop model. Various rainwater harvesting design scenarios were run for two different semi-arid areas, on different soil types to illustrate the application of the SWB model as a tool to help design the most appropriate rainwater harvesting strategy, taking into account whether arable land is limiting or not limiting for crop production. The SWB model was successfully calibrated. Simulation results reveal that in drier years bigger design ratios (cropping area: runoff area) of the in-field rainwater harvesting technique (IRWH) are most likely to be successful, while in wetter years smaller design ratios of the IRWH technique or even simpler rainwater harvesting strategies such as the tied ridge and the conventional tillage techniques can harvest sufficient rainfall for maximum crop production. Results from field trials conducted in Pretoria, on sandy clay loam soils, confirmed that, in a wet season, maize yield is maximized by a smaller IRWH design (1:1B). The SWB model can be used as a tool to help selecting the most appropriate rainwater harvesting strategy under specific conditions with minimum input requirements.

Thesis (M.Sc.(Agronomy)) --University of Limpopo, 2015
The changes in climate, especially poor rainfall patterns and distributions are key issues posing major agricultural challenges for food security and threaten the rural livelihoods of many communities in the Limpopo Province. Rainfall (P) is low and limited. These limited P is mostly lost through runoff and evaporation, which result in low soil moisture availability and possible crop failure. Therefore, techniques that reduce these water losses are important for improving dryland crop production and rainwater productivity (RWP). The objectives of this study were to determine the potential and effectiveness of rainwater harvesting and conservation techniques (RWH&CT’s) to conserve and improve plant available water (PAW) for dryland maize production and also determine the efficiency of the RWH&CT’s to improve dryland maize yield and RWP compared to conventional tillage (CON). The study was conducted over a period of two growing seasons (2008/09; 2009/10) using maize as indicator crop at the Towoomba Research Station of the Limpopo Department of Agriculture in the Limpopo Province of South Africa, on an Arcadia ecotope. The experiment was laid out in a randomized complete block design, with four replications and five treatments. The five treatments used in the study were; conventional tillage (CON), No-till (NT), In-field rainwater harvesting (IRWH), Mechanized basins (MB) and Daling plough (DAL). The IRWH and DL were classified as rainwater harvesting techniques (RWHT’s), whilst MB and NT were classified as water conservation techniques. Two access tubes were installed at each treatment to measure the soil water content (SWC) at four different soil depths of 150, 450, 750 and 1050 mm using the neutron water meter. The data collected included climatic data, soil and plant parameters. The data were subjected to analysis of variance through NCSS 2000 Statistical System for Windows and GENSTAT 14th edition. Mean separation tests were computed using Fisher's protected least significant difference test. The SWC of IRWH, DAL and MB were about 510 and 490 mm higher compared to CON and NT treatment during the 2008/09 and 2009/10 seasons, respectively. The PAWT of the IRWH, MB and DAL was significantly different from the CON treatment during the 2008/09 season. For both seasons the biomass yield of the IRWH treatment was significantly different from the NT treatment, producing 23 and 50% more biomass in the 2008/09 and 2009/10 growing seasons, respectively. The grain yield under IRWH was significantly different from the NT treatment during both 2008/09 and 2009/10 seasons. The highest maize grain yield of IRWH was achieved during the 2009/10 season with 56% higher grain yield than the NT treatment. RWP from various RWHT’s were significantly different from the NT treatment. These results indicate that IRWH and DAL were 12 and 2% more effective in converting rainwater into harvestable grain yield than the CON treatment. R2 values of 68.6 and 78.4% for SWC and transpiration (Ev) were obtained when correlated with maize grain yield respectively. This indicates the importance of moisture conservation for improved dryland maize production under low P areas. Therefore, the use of appropriate RWHT’s by smallscale farmers maybe crucial to improve dryland maize production. IRWH outperformed all other treatments in terms of the soil parameters and plant parameter measured during the period of this study. Therefore, these results suggest IRWH has potential of sustaining maize yields under low rainfall conditions. Key words: Rainwater harvesting, conservation techniques, ecotope, rainwater productivity, maize yield, precipitation use efficiency.

Thesis (MSc. (Horticulture)) -- University of Limpopo, 2018
Rainwater harvesting is an old age practice used in water-scarce rainfed crop production areas. It is practiced to supplement additional water for crops with insufficient amounts of rainfall for optimum production. The aim of this study was to assess yield responses of Swiss chard under In-field rainwater harvesting techniques (IRWH) and catchment areas. The trials were conducted at two sites, University of Limpopo experimental farm (Syferkuil) and on farmer’s field at Apel. The main plots were two catchment areas (2 m (1 m runoff strip plus 1 m basin)) and (3 m (2 m runoff strip plus 1 m basin)), while the subplots were five IRWH techniques namely; Control (farmers practice), Rainfed, IRHW (without mulch + irrigation), IRWH+Mulch and IRWH+Mulch+Irrigation. The results obtained showed no significant differences in yield of Swiss chard in relation to catchment areas of 3 and 2 m respectively. However, significant differences in plant height, plant vigour, number of leaves and chlorophyll contents were obtained under different IRWH techniques. Significantly, highest average plant height of 40.75 cm was obtained in IRWH+Mulch compared to Rainfed with the lowest average 28.50 cm at Syferkuil. A similar trend was obtained at Apel. There were significant differences in number of leaves under IRWH techniques; the highest mean of 16.00 was obtained in the control (farmers practice) treatment, while the lowest mean of 9.00 was obtained in IRWH treatment at Apel. At Syferkuil, significantly highest average number of leaves was obtained in the IRWH+Mulch+irrigation treatment, while the lowest average number of leaves was obtained in the rainfed treatment. Regarding the yield of Swiss chard, the significantly highest average yield was obtained under IRWH+Mulch+irrigation and 3 m catchment treatment combination which was 84.86 t ha-1 compared to 20.66 t ha-1 in rainfed and 3 m catchment treatment combination at Syferkuil. Similar trend was found at Apel with the highest average yield recorded in IRWH+Mulch+irrigation treatment combination. Hence, IRWH technique with mulch and irrigation could be adopted by growers in a water-scarce environment like the Limpopo Province of South Africa.

Dissertação de mestrado integrado em Engenharia Civil
Nas últimas décadas o crescimento populacional acelerado, aliado à progressiva impermeabilização de áreas inicialmente com características rurais, tem originado um significativo decréscimo da capacidade de infiltração das águas no solo, que tem como consequência direta o incremento do volume de água pluvial afluente à rede de drenagem. Esta realidade tem acarretado grandes modificações no ciclo hidrológico natural, conduzindo à ocorrência de situações de risco que chegam a pôr em causa a vivência humana. A presente dissertação dedica-se à avaliação de técnicas de aproveitamento de águas pluviais em comunidades urbanas e da forma como estas podem atuar como medida de mitigação de fenómenos de cheias e inundações. Neste contexto, caracterizam-se nove técnicas de aproveitamento de água da chuva em comunidades urbanas, identificando os seus princípios de funcionamento, benefícios e inconvenientes. Recorrendo a parâmetros de classificação que englobam as vertentes técnica, económica, ambiental e social, realizou-se uma análise comparativa através de uma matriz que permitiu aferir a relação de benefício entre cada uma das técnicas e os critérios definidos, possibilitando uma avaliação das técnicas mais vantajosas sob cada um dos pontos de vista. Posteriormente definiu-se um caso de estudo situado numa comunidade urbana pertencente ao concelho de Braga para implantação das técnicas de aproveitamento de águas pluviais mais vantajosas, em quatro cenários distintos, sendo que cada um deles está estreitamente relacionado com cada um dos parâmetros de comparação. Desta forma, foi possível avaliar os benefícios que adveem da implantação de cada uma delas num contexto real. As técnicas de aproveitamento de água da chuva revelam-se, assim, como medidas de implantação fulcrais em comunidades urbanas para a promoção da reutilização da água da chuva em diversos fins, para o aumento da taxa de infiltração da água com uma menor carga poluente, assim como para a atenuação dos picos de cheia devido à capacidade de retenção.
Trough the last decades, the population growth, associated with the increasing of waterproofing of rural areas, has led to a significant decrease of the water infiltration capacity trough the soil. This way, the volume of rainwater affluent to the drainage network is naturally suffering an increase. This situation has led to many changes in the natural hydrological cycle, leading to situations that can put in risk human lifes or their well being. This dissertation is dedicated to the evaluation of different rainwater harvesting techniques in urban communities and also to the wat they can be used as a mitigation measure for flood situations. In order to understand the benefits, disavantages and their way of operating, nine of the rainwater harvesting techniques in urban communities are characterized and studied in this work. By using a classification matrix that includes the technical, economic, environmental and social aspects, a comparative analysis was carried out through the relationship between each of the techniques and the defined criteria. Therefore, it was possible to make an evaluation of the most advantageous techniques, from each point of view. Subsequently, a case study was set up in an urban community, located in Braga, in order to implement the most advantageous rainwater harvesting techniques, in four different scenarios, each of which is closely related to each of the parameters of comparison. This way, it was possible to evaluate the benefits that come from the implementation of each of them in a real context. Thus, rainwater harvesting techniques are seen as serious measures in urban communities to promote the use of rainwater for various uses, to increase the rate of water infiltration in soils with a lower pollutant load, as well as measures for the attenuation of the flood maximum flow rates due to their retention capacity.

AbstractAgriculture has shown a considerable capacity to adapt to climate change. Many adaptations occur autonomously without the need for conscious response by farmers and agricultural planners. However, it is likely that the rate and magnitude of climate change may exceed that of normal change in agriculture that specific technologies and management styles may need to be adopted to avoid the most serious of effects. Thus areas likely to be most vulnerable to climate variability can be spared from its impacts through implementation of appropriate adaptation measures such as development of indigenous technologies.Six hundred farmers from the six geopolitical zones of Nigeria were surveyed and they all possess different indigenous adaptation strategies ranging from swamp farming (Oyo State), application of neem seed (Kaduna State), soil erosion control (Enugu State), rainwater harvesting (Taraba State), land improvement (Cross River State) to farmland management (Benue State). They all have simple but profound technologies driving these schemes with much success. These indigenous adaptation techniques are majorly constrained by inadequate financial resources. Indigenous technology adoption is affordable with high revenue potential.

Nowadays the world population increases, so the demand for clean water is rising. Rain is the faster resource that can recharge compared to ground water. Rainwater harvesting system (RWHS) is one of the traditional and easiest ways of rising fresh water supplies. This system already implements by many countries in the world as a viable decentralized water source. Malaysia can be classified as a country with high annual rainfall and high consumption of domestic water. Malaysia is well and strategically positioned to harvest rainwater for both potable and non-potable uses. This research describes the collaborative and development affordable technology for capturing and retaining runoff starting from rooftop gutter until the tank storage using as a valuable source of water and recharge the percolation well and increase ground water level. The developed system consists of soil sensor, integrated water pump, Arduino controller and water tank harvesting with dynamic mechanical flushing technique which improving filtration method. The results show that the system can be efficiently used for small-scale drip irrigation especially in urbanization farming as nowadays scenario of agriculture demand. Hopefully, this can be helpful as a valuable water source in future.

In arid and semi-arid regions, rainwater harvesting represents an important alternate source of water supply around the globe. The middle east is an integrally dry zone and due to climate change, it has experienced a severe drought for the last decade that made the situation worse. Many countries are suffering from awful water crises due to increasing water demand for agriculture and rapid urbanization. Therefore, unconventional water supply resources practices such as using rainwater harvesting for agricultural purposes can be possibly used to tackle water scarcity. Numerous researchers have established different criteria and methods to identify suitable sites selection techniques for rainwater harvesting (RWH). The main objective of this study was to determine the most commonly effective methods and techniques that have been practiced in the middle-east region to summarize the best methods for rainwater harvesting site selection. These effective common methods of multi-criteria analysis (MCA) were discussed accordingly in this review paper and based on the previous studies the best applicable method was the integration between (MCA) method and the GIS technique. The study employed a method of gathering and recording the main criteria and techniques which were established in the last thirty years. It compared and categorized the main methodologies from previous studies and practices from international organizations and scientific research and identified the most common characteristics and sets of criteria suitable for use in arid and semi-arid regions. The techniques were diverse based on biophysical criteria to methods including socio-economic criteria, precisely in the last two decades. The most effective and significant criteria for suitable site selection of RWH in the arid and semi-arid regions found are: land use/land cover, slope, type of soil, rainfall intensity, streams distant and the cost. The success of RWH selection sites tended to increase when these criteria are measured and based on these criteria. KEYWORDS: RWH Selection Suitability, Arid and semi-arid zones, Middle East, Agriculture, GIS, Multi-criteria analysis.
