Hydrograph Analysis-Rainfall and Time Trend (HARTT)

HARRT is an approach for statistically estimating trends in groundwater levels. The approach seperates the effect of atypical rainfall events from the underlying time trend and the lag between rainfall and its impact on groundwater is explicitly represented.

HowWet?

Using the principles of soil science, the HOWWET?computer program has been developed to provide a simple method of determining soil moisture and available nitrogen mineralisation through fallows using farm rainfall records.

HowOften?

HowOften? is a WINDOWS program that explores long-term rainfall records to find how frequently rainfall events occur. Some examples of applications include finding:How often planting opportunities occur and risk associated with opportunity cropping.

HowMuch?

The HowMuch? program is a WINDOWS based educational tool which uses rainfall records to estimate crop yields from crop Water Use Efficiency (WUE) and the Plant Available Water Capacity (PAWC) of your soil. It is an "open box" modelling environment in which growing season rainfall is adjusted by user defined weightings to compare the influence on yield of rainfall at various crop stages

How Leaky? How Murky? (HLHM)

Howleaky?is a simple, graphical interface to a daily water balance model. Its main purpose is to explore the effects of different vegetation (including crops, pastures and trees), climates, soil types and management on the water balance: evapotranspiration, runoff, and deep drainage. Erosion, sediment and pesticide movement are estimated.

Hillbelt

Simple spreadsheet model that aids design of belts of trees on hill slopes. Takes rainfall and seasonal distribution, slope, water use, depth of soil, and hydraulic conductivity and determines optimum width of belts and inter-belt spacing based on maximising water use and minimising planted area while minimising waterlogging.

Gypsy

Gypsy is a computer program designed to help Australian sugarcane growers make decisions on what rates of gypsum to apply to sodic soils. It is intended for use by advisory staff and growers, and should be used together with the CRC Sugar Technical Publications Diagnosis and Management of Sodic Soils under Sugarcane, and where necessary, the Field Guide for Diagnosis of Sodic Soils in the Australian Sugar Industry.

Grass Production Model (GRASP)

GRASP is one of the models used by AussieGRASS.  GRASP uses daily climate inputs to simulate the water balance (runoff, infiltration, soil evaporation, transpiration, and drainage), pasture growth (green growth, death, and detachment) and animal intake (diet selection, utilisation and live weight gain). Currently, a number of native and established improved pasture systems can be simulated with GRASP. Effects of trees on pasture production are also simulated.

Forest Cover Flow Change Tool

The Forest Cover Flow Change tool (FCFC) is designed to adjust a time series of observed or simulated daily flow to account for significant changes in forest cover. The model may be applied to catchments from 100 ha to 1,000 km2. The model is typically used to adjust inputs to larger scale catchment models.

FLOWTUBE

Catchment scale simple hydrogeologic model providing groundwater balance and discharge area mapping. FLOWTUBE is a relatively simple calculator for examining the effects of a range of recharge and discharge options on catchment groundwater. FLOWTUBE can assess long term trends in groundwater levels, and estimate rates of rise of groundwater, length of the flowtube with water at or near the catchment surface, and the periods of time over which ground water movements will take place. FLOWTUBE works on long-term average recharge values and does not provide accurate predictions of short term (decade or less) fluctuations.
