Water erosion in British farmers' fields. Some causes, impacts, predictions
The factors discussed are vegetation cover, soil surface roughness, rainfall amount and intensity, the morphology of the eroded field, soil type, crop type and how the land was worked by the farmer. Some geomorphological impacts are then described
. How these factors and impacts can be used to predict the occurrence and severity of rilling in British farmers' fields is then discussed.

The effect of farming upon solid transport in the River Almond, Scotland in Erosion et transports solides dans les eaux continentales.

In this study the erosion risk is estimated and related to existing land use. Farmers were interviewed and a soil erosion risk map was made.

are primarily due to industrial activities but not from soil parent materials and farming practices.

Exploratory study on how the farmer can decide, which of the three alternatives (soil map, soil analysis or their combination) should be used as a basis for predicting the most appropriate agricultural land use or management. It is illustrated

Nutrient loading models for coastal waters

The main objective in this work has been to develop load models/load diagrams for coastal areas where the environmental effect of nutrient discharges in general, and from fish farms in particular, can be related to the dose of nutrients (nitrogen

erosion or that factors such as the nature of the farming system exist which inhibit the delivery of suspended sediments obtained from basin slopes to river channels.

The formation of deep topsoils in Orkney

of formation which have led to the increase in soil depth. Results from transect and grid surveys indicate how the soil is thickest adjacent to old farms. The historical literature suggests a wide range of possible inputs from seaweed and calcareous sands

PREPARATION OF THE RIVER BED AND BANKS FOR MAINTENANCE WORK, AND RESIZING, RESHAPING AND CORRECTION OF THE RIVER BED HAVE MANY ADVERSE AND RELATIVELY FEW BENEFICIAL EFFECTS ON FISH LIVE AND ENVIRONMENT. TO PRESERVE FISH-FARMING INTERESTS, THEREFORE

from the growing scarcity of mineral resources, energy sources, groundwater, and farming land. Thus, the author has pointed out in several publications that part of our geoscientific research capability needs to be reoriented towards the future
