[1] We used statistical properties of drainage networks on Mars as a measure of martian landscape morphology and an indicator of landscape evolution processes. We utilize the Mars Orbiter Laser Altimeter (MOLA) data to construct digital elevation maps (DEMs) of several, mostly ancient, martian terrains. Drainage basins and channel networks are computationally extracted from DEMs and their struc...

The mathematical modeling of fracture networks is critical for the exploration and development of natural resources. Fractures can help the production of petroleum, water, and geothermal energy. They also greatly influence the drainage and production of methane gas from coal beds. Orientation and spatial distribution of fractures in rocks are important factors in controlling fluid flow. The obj...

Digital elevation models (DEMs) are a useful data source for the automatic delineation of flow paths, sub watersheds and flow networks for hydrologic modeling. Digital representation of the flow network is central to distributed hydrologic models because it encodes the model element linkages through which flow is routed to the outlet. The scale (drainage density) of the flow network, used contr...

Morphotectonic investigations were carried out by the use of morphometric indices which serve as a tool of identification in regions with active tectonic warp. Landforms in active deformation area are produced from relations of tectonic and surficial processes. One of the most significant landforms underground is rivers that are extremely responsive to tectonic movements mainly uplift and tilti...

Abstract Predicting the occurrence and spatial patterns of rainfall induced flash floods is still a challenge. Instant genesis typically smaller areal coverage are major impediments to their forecasting. Analysis morphometric parameters provides useful insight on hydrological response drainage basins high intensity events. This information valuable for understanding flood potential evading dest...

a study of changes in groundwater resources of najafabad plain is an important issue asregards water resources management, especially after dry becoming of zayandehroodriver. in the present study trend analysis was conducted on groundwater level of 33piezometeric stations, located in najafabad plain during 1374-1391 while using mann-kendall non-parametric test. the slope of trend line was estim...
