Assessment of Watershed Catchment Ecological Power with Taxonomy Method for Watershed Comprehensive Management (Case Study: Watershed Zydasht, Taleghan)
author
Abstract:
Nowadays watershed catchments have been introduced as the main point of permanent development in many management discussions. Watershed catchments ecological power assessment and their rankings according to different Ethological criteria is one of the important factors in watershed catchments planning and management. Taxonomy method is one of the most comprehensive planned systems for assessing the power of related variables in planning and decision making for the future. In this research, four subcatchments of Zidasht catchment located in Taleghan region has been selected. Based on Taxonomy method, four effective variables in watershed catchments management plans (plant composition index, soil protection index, erosion and sediment index, and water quantity index) has been selected. Results demonstrates that the most effective index is the soil protection index and the ranking and the first priority among four selected sub catchments to perform management plants according to four mentioned indexes is D1 zone. The most important indicator of soil conservation index, the D2 sub and DINT1 and DINT2 are next in priority.

This paper presents an ecological–economic model for a lake and its watershed systems. We describe the linkage between the watershed system and the lake aquatic ecosystem and the modeling process. The lake–watershed system was divided into six subsystems: social system, economic system, terrestrial ecosystem, lake water system, pollutant system, and lake aquatic ecosystem. The model equations w...

In the present study, the impact of watershed management practices on flood hydrograph characteristics was investigated using HEC-HMS model. In order to design, calibrate, and validate the model, data from a representative paired watershed (Kakhk Watershed, Khorasan Razavi Province, Iran) was collected and field surveys were performed to have the dataset further completed. Results of paired sam...

Increasing the use of water and soil resources in watershed in recent years and unproductive and inappropriate use of land ecology has exacerbated the occurrence of floods. In this context, watershed management is one of the most effective ways to cope with this crisis. This research quantify the results of these activities by calculating the decreased volume and discharge due to biomechanical ...

Environmental monitoring typically falls into one of two broad categories. Targeted designs, utilizing fixed stations, focus on describing and quantifying impacts, tracking trends, and assessing compliance with regulatory guidelines or limits. Probabilistic designs, in contrast, draw sampling stations at random from an area or region, and the stations are used to describe conditions in the regi...
