Skilful and reliable precipitation data are essential for seasonal hydrologic forecasting and generation of hydrological data. Although output from dynamic downscaling methods is used for hydrological application, the existence of systematic errors in dynamically downscaled data adversely affects the skill of hydrologic forecasting. This study evaluates the precipitation data derived by dynamic...

In this paper, we propose a method for the issue of identification for the variant pattern of hydrological series with variance variation: Breusch-Pagan test is used to check the inconsistency of the variance of the series, and Hydrological Variation Diagnosis System is designed to identify the variant pattern of variance. We take the third grade region on the upper reaches of Cetian Reservoir ...

In addition to geological, hydrological and hydrogeological invcstigations and $roundwater tracing, detailed surveyin of the groundwater quality IS becoming particular1 important for environmental impact monitoring on karst aquifers. &roundwater qualitydata contain NO types of information, i.e. the natural chemistry of water and its caused by anthropognicimpacts. The method of results presentat...

The environmental requirement of the river is the amount of water to maintain natural ecological conditions and health of quality of the river water. In this study, to estimate the environmental water requirement of Karoun River, Dez, Great Karoun and Beheshtabad sub-basin (upper Karoun) using hydrological Montana method and offers based on frequency analysis of hydrological flow normally and u...

River discharge is an important issue to be monitored because of its significant influence on environmental systems, on human lives for water resource exploitation, and hazards related to floods and landslides. In this context, we have designed and developed a web-based Geoportal for hydrological applications that integrates geospatial processing services and web mapping viewers to provide an i...

Understanding how hydrological and biogeochemical properties change over space and time in response to remedial treatments is hindered by our ability to monitor these processes with sufficient resolution and over field relevant scales. Here, we explored the use of geophysical approaches for monitoring the spatiotemporal distribution of hydrological and biogeochemical transformations associated ...

[1] This paper presents a distribution-free statistical test aimed at detecting gradual changes in the hydrological behavior of watersheds. The proposed test uses a rainfall-runoff model to identify watershed behavior over successive time periods and a resampling approach to quantify the significance of trends. The method can be applied with any model deemed suitable for the studied watershed. ...

The study objective is to extract HydroGeoMorphic Units in wetlands from LiDAR data estimating the required accuracy for assessing their functions in various hydrological and vegetation environments. Several Digital Terrain Models (DTMs) have been derived from LiDAR data with different point densities, ranging from 4 to 1 point/m2 with four interpolation methods. Then, the HGMU have been extrac...

Microbial community assembly and microbial functions are affected by a number of different but coupled drivers such as local habitat characteristics, dispersal rates, and species interactions. In groundwater systems, hydrological flow can introduce spatial structure and directional dependencies among these drivers. We examined the importance of hydrology in structuring bacterial communities and...
