“…Most of them face similar problems related to the unwise management of water resources: depleted aquifers [53], increased concentration of nitrogen and other pollutants [54,55], saltwater intrusion [56,57], and degradation of nearby natural environment [58][59][60]. The changing climate is only expected to exacerbate the problems, adding the risk of desertification in these areas [61].…”

Agricultural use is by far the largest consumer of fresh water worldwide, especially in the Mediterranean, where it has reached unsustainable levels, thus posing a serious threat to water resources. Having a good estimate of the water used in an agricultural area would help water managers create incentives for water savings at the farmer and basin level, and meet the demands of the European Water Framework Directive. This work presents an integrated methodology for estimating water use in Mediterranean agricultural areas. It is based on well established methods of estimating the actual evapotranspiration through surface energy fluxes, customized for better performance under the Mediterranean conditions: small parcel sizes, detailed crop pattern, and lack of necessary data. The methodology has been tested and validated on the agricultural plain of the river Strimonas (Greece) using a time series of Terra MODIS and Landsat 5 TM satellite images, and used to produce a seasonal water use map at a high spatial resolution. Finally, a tool has been designed to implement the methodology with a user-friendly interface, in order to facilitate its operational use.

“…In recent times, detailed high‐resolution three‐dimensional views of the earth surface have become available that have led to detailed geographical investigations. In the case of watersheds, the land‐use changes, drainage network and variation of water both in terms of quality and quantity are determined through RS utilizing satellite images (Musaoglu et al 2005; Goksel et al 2006; Kaya et al 2007; Cetin et al 2008; Coskun et al 2008). Besides, GIS provided a wide study area to analyse various layers that are stored and updated together with attributes and spatial information of any geographical surface.…”

Diffuse pollution has a complex nature depending on various land-use activities like agriculture, livestock breeding and forestry. In this study, an alternative methodology is applied for decreasing the spatial uncertainty of diffuse nutrient load estimations. It is applied in the Melen Watershed, Turkey, which is an important watershed from where additional water will be supplied for the megacity Istanbul via interbasin water transfer. Monthly diffuse nutrient loads were estimated for each subwatershed by utilizing remote sensing (RS) and geographical information systems (GIS). Estimated nutrient loads were considerably different in various months due to the temporally irregular fertilizer application and meteorological conditions. Temporal differences were also predicted in the spatial distribution of the nutrient loads. The methodology is applicable in watershed protection studies, especially where necessary etudes should be conducted in the short term and with limited data. Such efforts in identifying and determining the diffuse loads are important for sustainable management of the watershed.

“…Also, some research has focused on water resource planning and management and hydrologic modeling using GIS modeling [22][23][24][25]. The main difference between previous studies and the present study is that there has been no comprehensive study to date involving the application and assessment of GIS-based multi-criteria analysis, including WLC and fuzzy logic methods to identify the suitable sites in a water reservoir, especially in Malaysia.…”

The purpose of this study is to compare the weighted linear combination (WLC) and fuzzy logic (FL) models in identifying the most suitable location for a water reservoir in the area of Batu Pahat, Johor, Malaysia. First of all, parameters important to a water reservoir for the studied area were identifi ed. Then maps of the study area were prepared and integrated. The main criteria selected for this study are pipe line, elevation, rive, land use, road network, water supply network, and slope. Suitable locations for the water reservoir were selected using each model. The results of this study indicated that the FL method in the early stages had better decision-making powers for locating water reservoir sites when compared to the WLC method. The appropriate places for water reservoir construction based on two models were located to the northwest and west of the study area. The two models are validated using the Kappa index. According to the results of the validation method, the map produced by the FL method exhibits satisfactory properties in the study area. Thus, it can be concluded that the results derived from two models (WLC and FL) integrated in ArcGIS can be a useful tool in GIS analysis for the determination of suitable locations for water reservoir in the study area.
