| dehydrated sludge (Sludge whose water content has been reduced by physical means) | atūdeņojušies nosēdumi | |
| delegated management (The process of assigning or transferring authority, decision making or a specific administrative function from one entity to another) | deleģēta vadība | |
| deletion | dzēšana | |
| delta (A delta is a vast, fan-shaped creation of land, or low-lying plain, formed from successive layers of sediment washed from uplands to the mouth of some rivers, such as the Nile, the Mississippi and the Ganges. The nutrient-rich sediment is deposited by rivers at the point where, or before which, the river flows into the sea. Deltas are formed when rivers supply and deposit sediments more quickly that they can be removed by waves of ocean currents. The importance of deltas was first discovered by prehistoric man, who was attracted to them because of their abundant animal and plant life. Connecting waterways through the deltas later provided natural routes for navigation and trade, and opened up access to the interior. Deltas are highly fertile and often highly populated areas. They would be under serious threat of flooding from any sea-level rise) | delta | |
| demand (The desire, ability and willingness of an individual to purchase a good or service. The consumer must have the funds or the ability to obtain funds in order to convert the desire into demand. The demand of a buyer for a certain good is a schedule of the quantities of that good which the individual would buy at possible alternative prices at a given moment in time) | pieprasījums | |
| demesnial water (A body of water that is owned and maintained by a national governmental body or agency) | ūdenstilpe, kas atrodas valsts īpašumā | |
| democracy (A system of governance in which ultimate authority power is vested in the people and exercised directly by them or by their freely elected agents) | demokrātija | |
| demographic development (Growth in the number of individuals of a population) | demogrāfiskā attīstība | |
| demographic evolution (The gradual pattern of change in the growth of human populations in a particular region or country, from a rapid increase in the birth and death rates to a leveling off in the growth rate due to reduced fertility and other factors) | demogrāfiskā attīstība | |
| demography (The statistical study of human vital statistics and population dynamics) | demogrāfija | |
| demolition business (The activity of reducing buildings or other structures to rubble) | uzņēmējdarbība ēku nojaukšanas jomā | |
| demolition waste (Masonry or rubble wastes arising from the demolition of buildings or other civil engineering structures) | būvgruži | |
| demonstrability (No definition needed) | pierādāmība | |
| demonstrability (No definition needed) | rādītspēja | |
| demonstration | demonstrējuma projekts | |
| dendrochronology (The science of dating the age of a tree by studying annual growth rings. It is also employed to interpret previous environments and climatic variations by examining certain kinds of trees. It is based on the theory that the width of the growth ring reflects the amount of rainfall and the temperature of the year in which it was formed) | dendrohronoloģija | |
| dendrometry (The measuring of the diameter of standing trees from the ground with a dendrometer that can also be used to measure tree heights) | dendrometrija | |
| denitrification (1. The loss of nitrogen from soil by biological or chemical means. It is a gaseous loss, unrelated to loss by physical processes such as through leachates. 2. The breakdown of nitrates by soil bacteria, resulting in the release of free nitrogen. This process takes place under anaerobic conditions, such as are found in water-logged soil, and it reduces soil fertility) | denitrifikācija | |
| denitrification of waste gas (Current methods for controlling NOx emissions in motor vehicles include retardation of spark timing, increasing the air/fuel ratio, injecting water into the cylinders, decreasing the compression ratio, and recirculating exhaust gas. For stationary sources, one abatement method is to use a lower NOx producing fuel or to modify the combustion process by injecting steam into the combustion chamber) | izplūdes gāzu denitrifikācija | |
| density (The mass of unit volume of a substance) | blīvums |
