Conceptual PHES-system models of the Aysén watershed and fjord (Southern Chile): testing a brainstorming strategy.
نویسندگان
چکیده
The use of brainstorming techniques for the generation of conceptual models, as the basis for the integrated management of physical-ecological-social systems (PHES-systems) is tested and discussed. The methodology is applied in the analysis of the Aysén fjord and watershed (Southern Chilean Coast). Results show that the proposed methods can be adequately used in management scenarios characterized by highly hierarchical, experts/non-experts membership.

Estimation of Runoff using Modified SCS Models
In recent decades, due to the importance of watershed management programs and the need for adequate information and correct estimation of rainfall and runoff, many conceptual models have been proposed. These models have parameters that must be estimated according to observational data. However, finding the optimal values for the parameters of simulation models has always faced uncertainty. One ...
متن کاملواسنجی و تحلیل عدم‌قطعیت یک مدل نیمه‌توزیعی در یک منطقه نیمه‌خشک
Application of conceptual hydrological models is an important issue in watersheds for researchers, especially in arid and semi-arid regions. The hydrological behaviors are complicated in such watersheds and their calibration is more difficult. In this article, the conceptual and semi-distributed SWAT model is used for a semi-arid Nishabour watershed with 9350 km2 area. Streamflow simulation is ...
متن کاملComparison of Efficiency for Hydrological Models (AWBM & SimHyd) and Neural Network (MLP & RBF) in Rainfall–Runoff Simulation (Case study: Bar Aryeh Watershed -Neyshabur)
For suitable programming and management of water resources, access to perfect information from the discharge at the watershed outlet is essential. In most watersheds, the hydrometric station is not available; then, different models are used to simulate the discharge within watersheds without data. The selection of preferred model for rainfall- runoff simulation depends to the purpose of modelin...

BACKGROUND AND OBJECTIVES: The goal of this study is to evaluate in a time-series study the short-term effects of particulate matter-2.5exposure on respiratory emergency visits in six central-southern Chilean cities highly contaminated by wood smoke. METHODS: Association was assessed using both distributed lag linear and non-linear Poisson models constrai...
متن کاملConceptual and numerical models of the evolution of pedogenic carbonates in soils of arid and semi-arid regions: A review
Introduction Calcareous soils are widely distributed in arid and semi-arid regions of the world and the presence of carbonates in the soils affects both physicochemical properties and the pedogenic evolution. In addition, soil carbon plays a critical role in the global carbon cycle, and pedogenic carbonates are an important sink for atmospheric carbon. Pedogenic carbonates are also the proxy o...
