Otros contactos: Haimanote K. Bayabil ySandra M. Guzmán

Like any other moving fluid, flowing water has momentum. When subjected to a sudden change in flow, shock waves propagate through the system. This occurrence is referred to as "water hammer." Flow changes can occur due to operation of valves, starting and stopping of pumps, or directional changes caused by pipe fittings. The intensity of water hammer e

Home Irrigation and Landscape Combinations for Water Conservation in Florida

Melissa B. Haley, Michael D. Dukes, Bernard Cardenas, Grady L. Miller, and Dorota Z. Haman

This publication summarizes a study whose objectives were to determine the amount of residential irrigation water use in central Florida, and to evaluate if combinations of irrigation scheduling and landscape/irrigation design could reduce irrigation water application. Written by Melissa B. Haley, Michael D. Dukes, Bernard Cardenas, Grady L. Miller, and Dorota Z. Haman, and published by the UF/IFAS Department of Agricultural and Biological Engineering, revised September 2024.

White paper from the UF/IFAS Vegetable Fertilizer Task Force, identifies differences between actual fertilization practices and UF/IFAS fertilizer recommendations, especially for vegetables grown with subsurface (Central and South Florida) and overhead (Miami-Dade County) irrigation. The recommendations of the VFTF aim at bridging the gaps between science-based results and the diversity in production systems found in the Florida vegetable industry.

Selecting a Method for Sealing Ponds in Florida

Dorota Z. Haman, Fedro S. Zazueta, Gary A. Clark, Sandra M. Guzmán, yHaimanote K. Bayabil

A pond can be created by constructing a dam or embank- ment across a watercourse, by excavating a pit or dugout, or by building a dike around a natural depression area. For many farms, ponds may be the most economical way to provide water for various agricultural operations. Necessary water for irrigation, livestock or fish production, or other purposes can be stored in the pond. Ponds can also be used to store runoff from irrigation or rainfall events. The use of this surface resource could lead to reduced pumping from deep aquifer water  supplies.
