Intensity-duration-frequency relations are shown in
Table 1.
Herd management
The herd size should be reduced to a number that can be supported with the available resources.
The minimum number of heifers should be retained, and the rest should be sold.
Segregating animals gives each class a better chance of getting needed feed supplies. Vulnerable
classes can be segregated and given preferential treatment. The older dry cows can be moved to the
poorer forage fields.
Use of a drought-affected paddock can be optimized by providing local water facilities and supplemental
hand feeding.
Conservation practices
Water retention and detention structures capture storm-water runoff which can be used for a variety of purposes.
Windbreaks and shelterbelts help in reducing wind velocity and therefore, evaporation and evapotranspiration.
Rainwater harvesting can be accomplished for immediate or eventual use in irrigation or drinking water for livestock.
Landscape contouring and terracing can be implemented where feasible to reduce runoff and direct excess moisture
into areas planted with trees, shrubs, and grass
(Fig. 1).
