Spatial Water Balance Modelling for Targeted Perennial Planting in South Western Australia
نویسنده
چکیده
A common strategy in mitigating secondary salinity in southern Australia is the planting of trees and other deep-rooted perennial vegetation. Planting needs to target areas where perennials will provide the most benefit by minimising runoff and groundwater recharge. A number of one-dimensional (1D) water balance models have been developed in Australia that predict water balance components (evapotranspiration, runoff, soil water storage and deep flow), based on climate data and soil/land use at a location. In Western Australia (WA), the Department of Agriculture (DAWA) has developed a simple model, AgET, that is tailored to the local soils and land uses (based on field-measured hydrological parameters), and is easily customisable.

Preliminary Evaluation for Vacuum Membrane Distillation (VMD) Energy Requirement
The energy requirement of vacuum membrane distillation (VMD) with or without recirculation was modelled using both experimental results and theoretical data. The trends are generally consistent between the theoretical and experimental data. Thermal energy contributes the most to the total energy required for the VMD process. To lower the thermal energy cost, waste heat resource and heat recover...

Few field measurements are available to constrain the diffuse discharge (or vertical leakage) component of the water balance of the Great Artesian Basin (GAB), even though numerical modelling indicates that it accounts for over half of the outflow of the GAB in South Australia. High leakage rates are observed along the southwestern margin of the GAB where the aquifer is close to the surface wit...

The main portion of water demands of arid regions like Kashan Plain, Iran supply by groundwater wells. This research was conducted to assess the groundwater quality as well as modelling and mapping groundwater quality in the study area using geosatistics and deterministic techniques. Five water quality parameters, including Electrical Conductivity, Sodium Adsorption Ratio, Total Hardness, ...
متن کاملHydrodynamic Modelling of Coral Reefs:Ningaloo Reef-Western Australia
As with all coral reef systems, the ecology of Ningaloo Reef is closely linked to water circulation which transport and disperse key material such as nutrients and larvae. Circulation on coral reefs may be driven by a number of forcing mechanisms including waves, tides, wind, and buoyancy effects. Surface waves interacting with reefs have long been known to dominate the currents on many coral r...
متن کاملField estimates of groundwater discharge – Great Artesian Basin, South Australia
Understanding the water balance of large groundwater systems is fundamental for the sustainable management of the resource. However, measuring many of the major components of the water balance pose considerable challenges and are thus estimated through modelling. A shortcoming of the modelling approach is that the water balance may have high bias and uncertainty due to insufficient information....
