Today the knowledge of physical parameters of a basin is essential to know adequately the rainfall-runoff process; it is well known that the specific characteristics of each basin such as temperature, geographical location, and elevation above sea level affect the maximum discharge and the basin time response. In this paper a physically based model has been applied, to analyze water balance by evaluating the volume rainfall-runoff using SHETRAN and hydrometric data measurements in 2003. The results have been compared with five ETp different methodologies in the Querétaro river basin in central Mexico. With these results the main effort of the authorities should be directed to better control of land-use changes and to working permanently in the analysis of the related parameters, which will have a similar behavior to changes currently being introduced and presented in observed values in this basin. This methodology can be a strong base for sustainable water management in a basin, the prognosis and effect of land-use changes, and availability of water and also can be used to determine application of known basin parameters, basically depending on land-use, land-use changes, and climatological database to determine the water balance in a basin.

Krueng Aceh River Basin area (Krueng Jreue Sub-watershed) is a critical watershed, including a priority basin I of 23,218.06 ha. The research was conducted in Krueng Aceh River Basin (DAS), Krueng Jreue Sub-district of Aceh Besar. The study was conducted from December 2015 to February 2016. The research used Descriptive method with field survey and analysis in labotarium. This study aims to analyze the water balance of land in Krueng Jreue Sub-watershed. The methods used in the calculation of the water balance are Thornthwaite & Mather (1957). The results showed that the average water availability in Krueng Jreue Sub-watersheds on the highest land use varieties was found in November and the lowest in July. The rainfall surplus occurred from October to April (7 months) and the deficit occurred from May to September (5 months). In various types of land use, ground water averages are quite available from October to May (8 months), while less available in June until September (4 months). The highest percentage of groundwater was found in the primary forest (47.20%), while the lowest was in the bush (36.36%)

Changing climate and land-use practices influencing the natural stream flow processes in the Naryn river basin of Kyrgyzstan. Variations in stream flow regime over 33-years (1980 to 2012) were investigated using daily discharge data of three hydro-stations (Naryn, Ych-Terek and Uzunakmat), located in the Naryn River Basin. Mean monthly discharge (MMD), mean annual discharge (MAD), standard deviation (SD) and coefficient of variation (CV) were calculated to know the spatio-temporal variability. Similarly, Pearson’s correlation coefficient (r) was used to know the relationship between discharge and rainfall. Advanced time-series graph, exceedance probability and frequency distribution were computed using Hydrognomon (V.4.0.3) software to observe the variability and trends in discharge. The results from statistical calculations and software-based computations highlight the monthly, annual, and long term spatio-temporal discharge variability, extreme events, distribution and changes in stream flow records. This study preciously creates the frequency and trends of seasonal discharge, annual discharge cycle, and range of highest and lowest discharge flows. The weak and negative relationship (-0.2121, -0.4238) between rainfall and discharge propose for more investigation of climatic parameters and the topography of Tian Shan Mountain perhaps influencing discharge variability due to melting of glacier at high altitude. The flow regime of the Naryn river basin over the past 33-years perhaps changed due to climatic fluctuations, with the seasonal snowmelt timing (Post-Spring, Summer, Pri-Autumn), precipitations period (March-October), and large-scale land-use alterations.

Abstract Assessment of the land use impact on the processes of water balance in the river basin should be an indispensable part of integrated river basins management. This paper compares climatic conditions occurring during the long-term period (1951-1980), following the situation immediately after dry conditions (1993-1999) and extremely rainy dates (2009-2012) with emphasis to estimate the runoff components in the Žitava river basin: the Obyce sub-catchment, situated in its upper part (74.5 km2) in the Slovak Republic. Modelling of the land use change effect on the total hydrology balance of the river basin characteristics was performed using the hydrological model WaSiM-ETH. The model was applied to evaluate the vegetation type influence and the water balance change in the presently mostly forested river basin (1), altering its replacement by the permanent grasses (2) and bushes (3), with emphasis to different total water balance characteristics change. The present state land use data were taken from the Corine Land Cover of the Slovak Republic. Model results show that actual evapotranspiration would decrease from -1.3% in case of bushes in 2009 up to -32.5% in case of grass in 2011. However, 13.3% rise was considered for bushes in 2010. Total annual discharge shows its increment in all observed changes from 5.9% for bushes in 2010 up to 65.3% for grass in 2012. Only in case of bushes in 2011 there was observed slight decrease of about -3.1%. Regarding the very expected land use change, especially in connection with the ongoing global climate change, the estimation of the hydrology balance components is of utmost significance.

Land Use Development

Abstract The long-term development of water bodies is investigated in this article using the cases of two river basins with similar natural conditions: the Kyjovka and Trkmanka River Basins in the Czech Republic. Using old topographic maps, land use development was assessed and the analysis of driving forces of land use changes was carried out. The essential land use changes in these areas are connected with the processes of agricultural intensification and urbanisation. The largest area of water bodies was recorded in both river basins in 1763. In the second half of the 19th century, the disappearance of most water bodies in the two basins was significantly affected by the above-mentioned driving forces. After World War II, some of the water bodies in the Kyjovka River Basin were restored and new ponds were established. In contrast, no significant water bodies were restored in the Trkmanka River Basin.
