Self help in soil conservation
Land is regarded by many people as the symbol of permanence - as a solid asset to pass on to succeeding generations. But farmers know, or should know, that soil is not static. They know that erosion by water and wind can cause good soils to become wastelands, and that wise land use can initially poor soils into expanses
Irrigation: Soil-Plant-Water Relationships
Soil-Plant-Water relationships describes those properties of soils and plants that affect the movement, retention, and use of water essential to plant growth. This publication attempts to provide engineers the basic data necessary to plan and maintain efficient conservation irrigation practices to provide a permanent irrigated agriculture engineering principles and research findings have been screened to give emphasis to the information needed to design, install, and operate irrigation systems on farms or groups of farms
SCS Natinoal Engineering Handbook: Section 15, Irrigation, Chapter 9--Measurement of Irrigation Water
Measurement of Irrigation Water describes the various methods of measuring irrigation water that are commonly used on irrigated farms. Tables and charts giving rates of flow for various structures and measuring devices are included. It is intended for use by Soil Conservation Service engineers providing assistance to individual farms or groups of farms
Sevier River Basin Floods 1852-1967
This chronology of Sevier River Basin floods extends from 1852 to
1967. Most common and destructive are dry mantle floods, which flow as
a muddy mortar-like substance containing 40 to 55 percent water. Hundreds
of tons of protective topsoil are removed from watershed lands,
debris and boulders are picked up as the flow travels down steep stream
channel gradients, and then the flood is debouched into communities and
on to productive cropland
Iowa sprinkler irrigation guide
This guide was prepared for technicians who design sprinkler irrigation systems. In addition , detailed basic data on soils , crops and water together with information on accepted principles of irrigation are given in tables as guides to the designer of sprinkler irrigation systems.https://lib.dr.iastate.edu/specialreports/1009/thumbnail.jp
