V Determination of average annual rainfall in the Aguablanca stream watershed using GIS and IDW method

In this investigation is analized the average annual rainfall of the hydrographic basin of the Aguablanca stream through the data provided by the Institute of Hydrology, Meteorology and Environmental Studies (IDEAM) ranging from 1976 to 2016, because there aren´t pluviometric stations relatively close, the methodology is used IDW with the intention of interporlation results and have a calculation close to reality. it´s concluyed lhe average annual precipitation of this river is 1327.9 mm/year, a normal value for a river basin in a tropical zone, also calculating the amount of water volume, is possible to calculate the amount of evapotranspired water, parameters that vary according to temperature and type of vegetation.

AbstractSǎrǎţel River basin, which is located in Curvature Subcarpahian area, has been facing an obvious increase in frequency of hydrological risk phenomena, associated with torrential events, during the last years. This trend is highly related to the increase in frequency of the extreme climatic phenomena and to the land use changes. The present study is aimed to highlight the spatial and quantitative changes occurred in surface runoff depth in Sǎrǎţel catchment, between 1990–2006. This purpose was reached by estimating the surface runoff depth assignable to the average annual rainfall, by means of SCS-CN method, which was integrated into the GIS environment through the ArcCN-Runoff extension, for ArcGIS 10.1. In order to compute the surface runoff depth, by CN method, the land cover and the hydrological soil classes were introduced as vector (polygon data), while the curve number and the average annual rainfall were introduced as tables. After spatially modeling the surface runoff depth for the two years, the 1990 raster dataset was subtracted from the 2006 raster dataset, in order to highlight the changes in surface runoff depth.

Water resources planning and management of a region requires an understanding of the water balance in the region. The Soil and Water Assessment Tool (SWAT) with QGIS interface (QSWAT) has been used here to arrive at the water balance components in the Palapuzha watershed of Valapattanam river basin in Kerala. Valapattanam river drains an area of 1867 sq.km. with 456 sq.km. area in Karnataka State. The river basin receives an average annual rainfall of 3600 mm. The Palapuzha watershed drains an area of 237.25 sq.km with an average annual rainfall of 4562 mm. The QSWAT model has been calibrated and validated using data for a period of eight years (2000-2007) for which both rainfall and streamflow data are available. The model was successful in simulating monthly streamflow during the calibration and validation periods with Nash Sutcliffe efficiency and correlation co-efficient greater than 0.75 and percent bias less than 10%, showing that the model is very good for predicting streamflow in Valapattanam river basin. This calibrated model was used to arrive at the different water balance components in the Palapuzha watershed. The results obtained will be useful for the sustainable development and planning of the water resources system in the highland humid tropical watersheds

The Rasina River Basin is located on the territory of Central Serbia. The aim of this paper is to determine the amount and spatial distribution of water resources, that is, to establish the participation of altitudinal zones in the formation of the total runoff in the Rasina River Basin area upstream from the "Celije" reservoir. In terms of methodology, determination of water volume is based on four separated petrological-hydrological complexes. Average weighted specific runoff in a given territory is 9 l/s/km2. Metamorphites and magmatites are in the first place per participation in the total water runoff of 42.8 %. The second place belongs to sedimentary rocks that make 39.6 % of the total runoff . Unbound sediments participate in the total runoff value with 10.5 % and limestone with 7.1%.

State Of The Environment

Vietnam is considered as one of the countries having rich resources from forest and sea, with a high average annual rainfall. However, in view of IWRA, water volume per capita annually in Vietnam is lower than the standard for nations having water resources at average level. Vietnam was recognized by the World Wildlife Fund (WWF) as having three out of more than 200 biological zones of the world. Flora and fauna in Vietnam are very rich and abundant, but due to indiscriminate exploitation, along with weak management, biodiversity levels are significantly reduced. This is also one of the causes of environmental pollution and degradation in Vietnam, besides the impacts from production activities, population migration from rural areas to urban areas, rapid urbanization, climate change and sea level rise, etc. Việt Nam được coi là một trong những quốc gia giàu nguồn tài nguyên từ rừng và biển, có lượng mưa trung bình hàng năm cao. Tuy nhiên, lượng nước bình quân đầu người hàng năm ở Việt Nam thấp hơn so với tiêu chuẩn cho quốc gia có nguồn nước ở mức trung bình theo quan điểm của Hiệp hội nước quốc tế (IWRA). Việt Nam được Quỹ Quốc tế về Bảo vệ thiên nhiên (WWF) công nhận có 3 trong số hơn 200 vùng sinh thái toàn cầu. Hệ động thực vật ở Việt Nam rất phong phú, nhưng do vấn nạn khai thác bừa bãi, cùng với sự quản lý yếu kém, mức đa dạng sinh học đã bị giảm đáng kể. Đây cũng là một trong những nguyên nhân gây ô nhiễm và suy thoái môi trường ở Việt Nam, bên cạnh các tác động từ hoạt động sản xuất, di dân, đô thị hóa, biến đổi khí hậu và nước biển dâng, v.v...

The article presents the results of the field studies and observations that carried out on the territory of the hilly, low-mountain and foothill agro landscapes of the Kyzylsu-yuzhnaya (Kyzylsu-Southern) River Basin of Tajikistan. Taking into account the high-altitude location of households and the amount of precipitation in the river basin, the annual volumes of water accumulated with the use of low-cost systems of collection and storage of precipitation have been clarified. The amount of water accumulated in the precipitation collection and storage systems has been established, the volume of water used for communal and domestic needs,the watering of livestock and the amount of water that can be used to irrigate crops in the have been determined. Possible areas of irrigation of household plots depending on the different availability of precipitation have been determined. It has been established that in wet years (with precipitation of about 10%) the amount of water collected using drip irrigation will be sufficient for irrigation of 0.13 hectares, and in dry years (with 90% of precipitation) it will be possible to irrigate only 0.03 ha of the household plot. On the basis of the basin, the total area of irrigation in wet years can be 4497 ha, and in dry years only 1087 ha. Taking into account the forecasts of population growth by 2030 and an increase in the number of households, the total area of irrigation of farmlands in wet years may reach 5703 hectares,and in dry years – 1379 hectares. Growing crops on household plots under irrigation contributes to a significant increase in land productivity and increases the efficiency of water use of the Kyzylsu-yuzhnaya basin.

The spatial distribution of precipitation is one of the most important climatic variables used in geographic and environmental studies. However, when there is a lack of full coverage of meteorological stations, precipitation estimations are necessary to interpolate precipitation for larger areas. The purpose of this research was to find the best interpolation method for precipitation mapping in the partly densely populated Khorasan Razavi province of northeastern Iran. To achieve this, we compared five methods by applying average precipitation data from 97 rain gauge stations in that province for a period of 20 years (1994–2014): Inverse Distance Weighting, Radial Basis Functions (Completely Regularized Spline, Spline with Tension, Multiquadric, Inverse Multiquadric, Thin Plate Spline), Kriging (Simple, Ordinary, Universal), Co-Kriging (Simple, Ordinary, Universal) with an auxiliary elevation parameter, and non-linear Regression. Root Mean Square Error (RMSE), Mean Absolute Error (MAE), and the Coefficient of Determination (R2) were used to determine the best-performing method of precipitation interpolation. Our study shows that Ordinary Co-Kriging with an auxiliary elevation parameter was the best method for determining the distribution of annual precipitation for this region, showing the highest coefficient of determination of 0.46% between estimated and observed values. Therefore, the application of this method of precipitation mapping would form a mandatory base for regional planning and policy making in the arid to semi-arid Khorasan Razavi province during the future.
